Abstract

A tire pressure monitor system tool that stores information regarding a plurality of tire pressure monitor systems. The information may include procedures for resetting and diagnosing the tire pressure monitor system. The tool may include a storing module that stores the information and a displaying module that causes the information to be displayed on a display of the tool. The tool may enable a user to input data regarding a vehicle. Based on the vehicle data input by the user, the tool may determine a tire pressure monitor system installed on the vehicle using the information stored. Based on the tire pressure monitoring system installed on the vehicle, the tool may determine one or more reset or diagnostic procedures that may be performed by the tool. The tool may also reference the owner'"'"'s manual of the vehicle. The tool may also include an updating module that updates the information stored by the tool. The tool may also include an update interface that may be, for example, an RS232 port. The tool may interface with an electronic control unit of a vehicle.
